This is the jaw of a Zebra Shark (Stegostoma tigrinum), a distinctive species of carpet shark known for its striking appearance and docile nature. While juveniles display dark bodies with white stripes (hence the name "zebra"), adults develop a pattern of dark spots on a pale background, more resembling a leopard. The jaw is robust and slightly arched, containing numerous small, comb-like teeth arranged in multiple rows—ideal for gripping and crushing prey.

Location:
Found throughout the tropical Indo-Pacific region, from the eastern coast of Africa and the Red Sea to the western Pacific, including northern Australia and Southeast Asia.

Average Size:
Adults typically grow to about 2.5 m, though individuals can reach up to 3.5 m in length.

Family:
Stegostomatidae (Zebra Sharks)

Species:
Stegostoma tigrinum
(Note: formerly known as Stegostoma fasciatum)

Feeding and Jaw Function:
Zebra Sharks are nocturnal foragers, using their powerful jaws to feed on molluscs, crustaceans, and small fish. Their teeth are not sharp but adapted for crushing, enabling them to break through hard shells and exoskeletons. The jaw specimen reveals the specialised dentition and bone structure essential for their bottom-feeding lifestyle.

Movement and Sensory Features:
Although capable of swimming long distances, Zebra Sharks often rest on the seabed during the day. They use electroreception and a keen sense of smell to locate prey hidden in the sand.

Reproduction:
They are oviparous, meaning females lay large, leathery egg cases which attach to the seabed. Hatchlings emerge fully formed after several months, bearing the iconic striped pattern of juvenile Zebra Sharks.

Conservation Status:
Listed as Endangered by the IUCN. Major threats include habitat degradation, fishing pressure, and the aquarium trade. Conservation efforts focus on habitat protection and captive breeding programmes.
